. MACHINE FOR SHELLING CORN.

Specification of Letters Patent.

Patented Nov. 12, 1907.

Application filed June 12,1907- Serial No. 378,470-

To all whom 'it may concern:

' Be it known that l, Josnrn A. WILmNsoN, a citizen or the United States, resident of Hiawatha, in the county of Brown and State of Kansas, have made a .certain new and useful Invention in Machines for Shelling Corn; and I declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the invention, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure 1 is a side elevation of the invention. Fig. 2 is a section on the line 2-2, Fig. 3. Fig. 3 is a section on the line 3-3, Fig. 2. Fig. 4 is a perspective view of the supporting frame.

The invention relates to corn shelling machines, having for its object the provision of improved means of durable and eflicient character for the purpose.

The invention consists in the novel construction and combination of parts as hereinafter set forth.

In the accompanying drawings, illustrating the invention the letter a, designates a supporting frame,

shown in the present case as made from a single piece of bar metal, doubled at one end as at u, and having upward extending branches b, lying close together for a portion of itheir length one of such branches being bent laterally away from the other branch I), (which is vertical throughout its length), and then bent vertically again to form forked or bifurcated portions 0, which are provided with journal bearings for the reception of the rotatable operating shaft d, of the machine.

Secured to one end of the shaft d, at the smaller closed end thereof, is the shelling cone 0. The converging side walls of this cone are provided with radial slots f, four being shown, such side walls having radial outward extensions or wings g, secured thereto in any suitable manner, or formed thereon by casting. The slots f, are located interniediately of the ends of the cone and extend a substantial part of the length In order to adapt the device for operation upon ears of corn of varying sizes, the pivoted shelling blades are made of yielding character, each blade having at its forward end connection with a bolt 9', which passes strain and are liable to be broken off.

through an aperture of a laterally projecting lug j, of the radial wing extension 9, a coiled spring It, being located upon the bolt between such laterally projecting lug and a lug 7c of the shelling blade. A nut k upon this bolt serves for adjustment of the blade 19, and of the tension of the spring 7:. The operating or inner edges of the shelling blades have a converging relation to each other and are curved outward at their end portions at i, to facilitate the entrance of the ear of corn. The opposite or inner end portion of each blade is similarly curved, as shown at i.

In use the shelling blades are subject to considerable In the present case these blades are braced intcrinediately of their width throughout their length against the side walls of the radial slots of the cone. in this way, the securing connection of the shelling blades with the outward extending wings of the conei s relieved of strain, whereby a durable connection is obtained. A comparatively light, inexpensive, and yet durable and effective maehi no is the result. The operating shaft of the ma chine is provided with a suitable crank handle at its free or outer end, as shown at Z. The machine is designed to be secured to a suitable upright support by bolts passing through perforations of lateral integral extensions a", at the bottom of the branches 0/. In case the shelling blades become worn, they may be removed, and replaced by new blades.

Having thus described the invention, what I claim and desire to secure by Lett rs Patent is- 1. A machine for shelling corn, having a rotatable shaft, a hollow shelling cone, closed at its smaller end, which has connection with said shaft, the side walls of said cone having radial slots, radial wing projections at one side of said slots secured to the cone, shelling blades lilting in said slots having outward extending portions secured to said wing projections and inward extending portions for action upon the corn. and a supporting frame formed of an integral piece of metal having a doubling bend at its bottom, and upward extending branches lying close together, one of said branches having a laterally bent portion provided with an upward bend to provide separated journal bearings for said shaft, one of said branches having integral lateral perforated projections at its lower end.

2. A machine for shelling" corn having a rotatable shaft, a hollow shelling cone secured thereto at one end, the side walls of such cone being provided with radial slots located intcrniediately of the ends of the cone and extending a sub stantial part of the length thereof, radial wing projections carried by the cone at one side of such slots, shelling blades fitting in such slots and having outer portions extending beyond the cone, pivoted at their rear. ends to said wing projections, and having zi yicldable connection at their forward ends with the wing projections.

3. A machine for shelling corn having a rotatable shaft, a hollow shellingcone secured at one end thereto, the side walls of such cone being provided with radial slots located intermediately of the ends of the cone and extending a sub stantial part of the length thereof, radial wing projections carried by the cone at one side of such slots, such Wing projections having each a laterally projecting lug at its forward end provided with an aperture, shelling blades fitting in said slots, having outer portions extending beyond the cone pivoted at their rear ends to said Wing projections and having at their forward ends laterally pro jecting lugs, bolts carried by the lugs of said blades and bolts.

coiled springs upon said In testimony whereof I afilx my signature, in presence of two Witnesses.
